Image capturing device

Abstract

An image capturing device includes a circuit board, an image capturing module, a light source module disposed on the circuit board and a connection body disposed above the light source module. The image capturing module has a first lens set and a second lens set disposed on the circuit board. The connection body has a first connection section having a first open end and a second open end. The first open end of the first connection section abuts against the light-emitting component or the upper side of the circuit board in adjacency to the light-emitting component. The first and second open ends together define a first light passage. The light-emitting component is positioned in the first light passage. The image capturing device can effectively avoid light leakage of the image.
